Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469146, here are decompositions:

5 + 469141 = 469146
19 + 469127 = 469146
47 + 469099 = 469146
109 + 469037 = 469146
137 + 469009 = 469146
163 + 468983 = 469146
173 + 468973 = 469146
179 + 468967 = 469146

Showing the first eight; more decompositions exist.
